Patented July 9, 1940 UNITED STATES PATENT OFFICE MACHINE FOR MAKINGPURELY PRESSED GLASSWARE Application September 11, 1936, Serial No.100,246 Renewed December 16, 1939 i 6 Claims.

This invention relates to a machine for making either blown or purelypressed glassware. By 'purely pressed glassware is meant ware which isproduced solely by pressing without the 5 application of any air for thepurpose of shaping the ware being produced.

The general object of the invention is to provide means whereby afeeder-fed glassware form ing machine for producing glassware by thenar- 10 row neck method may .also be employed for producing purelypressed ware, thus increasing the utility of such machine. For thepurpose of simplicity, the feeder-fed forming machine operating on thenarrow neck principle is referred to hereinafter as the narrow neckmachine or type of machine, and the type of ware produced on saidmachine is referred to as "narrow neck ware, irrespective of whether theware has narrow necks, this term identifying the ware by the method andmachine on which it is made.

A more specific object of this invention is to employ a narrow neckmachine for making purely pressed ware by utilizing certain of the partsof such machine heretofore used only for actuating the narrow neckforming instrumentalities, for actuating pressing and pressed warehandling instrumentalities. For this purpose, it is preferred to usepressing means which can readily be attached to and removed frompermanent operating parts of the narrow neck machine so that the narrowneck forming instrumentalities, which as usual are removable, may bereplaced when desired. It has been found in practice that in this waythe machine can be changed from the production of narrow neck ware tothe production of purely pressed ware (or vice versa) in normaljob-change time, that is, within the period usually necessary to changemolds and other parts when the machine is used only in the production ofdifferent kinds of narrow neck ware.

Other objects of the invention will be brought in, or will becomeapparent from, the description of an embodiment of the invention illus-.trated in the accompanying drawings, wherein:

Figure 1 is a view in vertical sectional elevation of a portion of anarrow neck machine embodying the invention, parts being omitted forclarity in illustration;

Fig. 2 is a similar view on enlarged scale, showing in detail the meansfor pressing the ware;

Fig. 3 is a view similar to Fig. 2, but showing in detail means forreceiving, cooling and discharging the pressed ware from the machine;and

Fig. 4 is a view illustrating the operation 01 supporting and cooling anarticle of ware in preparation for its discharge from the machine.

For purposes of illustration and not in limitation of the invention, theillustrated embodi- 5 ment (Fig. 1) consists of the adaptation of theinvention to one section of the Hartford Individual Section Machine,disclosed in the patent to H. W. Ingle, No. 1,911,119, dated May 23,1933, it being understood that the same adaptation may be made to anynumber of sections of such machine.

As shown in Fig. 5 of the Ingle patent, each section of such machinecomprises a blank mold and neck pin located at the blank forming stationand with which cooperate a delivery funnel,

a settleblow head and a neck mold. These and the other narrow neckforming devices are re-' movably attachedto their respective operatingmembers for the purpose, but only for the purpose, of substituting,other similar devices in changing from the production of one size orstyle of narrow neck ware to another.

Similarly, as shown in Fig. 1 herein, the base of the machine 6 supportsvertical shaft 1 for the holders, one of which appears at 8 which inIngle carry the blank mold sections. At 9 is shown what in Ingleconstitutes the neck pin operating mechanism, at H (Fig. 2) Ingle'sfunnel carrying arm, (in which funnel l2 of the present invention isremovably secured by ring l3), at I4 an arm similar to Ingle'ssettle-blow head arm and at I5 Ingles inverting neck mold carrying andtransfer arm.

Each section of the machineof the patent also includes a blow mold atthe finish blowing station and hence Fig. 1 herein shows the verticalshaft I 6 for the sections of such mold of the patent (not shown), andthe member H for tilting the blow mold bottom plate (not shown) of 40the patent. Also shown atthis station is a fin-. ish blow head I8 andFig. 1 shows at IS the finish blow head operating arm both substantiallyas shown in the patent to Ingle.

The operation of the actuating or carrying members ofthe narrow neckmachine will be explained hereinafter, it being desired first todescribe the utilization of such members in the operation of pressingand pressed ware handling .devices.

Referring to Figs. 2 and 3, it will be seen that. the neck mold carryingarm has removably fitted therein a sectional holder, as indicated at 2|,which carries the sections of pressing mold 22, and a solid mold bottomor closure 23, to form 65 a mold cavity of the shape desired, in thisinstance for forming a threaded fuse case. The mold bottom 23 has a lug29 thereon which is received in an opening 25 of the neck pin mechanism9, whereby the latter serves to center the mold bottom and the mold 22for registration with pressing ring 26. As will be apparent from Fig. 2,mechanism 9 serves as a support or rest for the pressing mold during theoperation of pressing.

Ring 26 is secured in and forms part of funnel l2 by screw means, asshown, and these parts receive therethrough pressing plunger 21, for theoperation of which the plunger carrying arm I4 is employed.

The plunger assembly includes casing 28 removably secured in knownmanner in the arm It, as by means of lugs and flanges or a bayonetjoint, as partially shown, this casing containing spring pressed plungersleeve 29 which fits into funnel l2 and in which plunger carrier 3| isslidably mounted under pressure of spring 32 in cage 33 on the casing.The downward movement of the plunger assembly is stopped by spring 34engaging shoulder 35, the degree of pressure applied to the plungerdepending upon the strength of spring 32, as will be understood.

To insure that the mold sections 22 will remain closed during thepressing operation, the blank mold carrying arms 8 (Fig. 2) are employedas a mold lock to the holders 2| for the mold sections.

The funnel carrying and plunger carrying arms I I and M are oscillatedand lowered by the shafts upon which they are mounted by means shown indetail in the Ingle patent. Said patent likewise discloses means forvertically adjusting the neck pin operating mechanism 9 which isheld infixed position for centering the mold bottom 23, and the means foroperating holders 8, as well as the mechanism for inverting arm l5. Suchmechanism is partially shown in Fig. 1 and includes oscillating shaft 31carrying gear 38 engaged by rack 39 which is reciprocated by a piston(not shown) in cylinder 4|.

The mechanisms for oscillating and lowering finish blow head 18 and thebottom plate carrying member I! also are shown in detail in the Inglepatent. The functions of these members in making pressed ware are asfollows.

The inverting of arm I5 inverts the press mold into the position shownin Fig. 3 in registry with discharge member 43 which replaces the blowmold at the finish blowing station, whereupon the finish blow head islowered to engage opening 42 therein with lug 24 on the mold bottom 23for centering the latter and stripping the pressed article from mold 22.At this position, the mold is opened in the same way as in releasing ablank for a narrow neck article, preferably by the 7 means provided inthe Ingle patent for opening the neck ring of the narrow neck machine.This serves to deliver the pressed article to the ware cooling anddischarge device 43.

This device 63 is removably secured to the bottom plate carrying memberll by a bayonet joint indicated at M, and its upper end is shaped toconform to the interior of the pressed article, as indicated at 45. Inorder to support and cool the pressed article, and out' of contact withmember,

33, an air jet is delivered through orifice 46 in member 43 into thecavity of the article. This serves to hold the article out of chillingcontact with the discharge member 43, as illustrated 'in Fig. 4. Whileso held, cooling air may be applied to the article from opposed nozzles41-41.

aecaera Thus the article is cooled both internally and externally. Whencooled to the desired degree, discharge member 93 is moved'verticallydownwardly to clear the mold 22 and then tilted by the operation of themechanism normally used for lowering and tilting a bottom plate. Thedetails of such mechanism may be best understood by reference to theIngle patent. It is sufiicient to explain here that member I! is pivotedat 48 and is held in horizontal position by spring 49 until movedvertically downwardly the length of slot 5|, whereupon member I! istilted into the dotted line position of Fig. 3. These operations arecaused by a piston (not shown), the rod 52 of which is connected tomember I! by links, one of which appears at 53. Such movement deliversthe article to a slide 54 having a slot 55 therein, through which worksdischarge device 43. The article comes to rest on a dead plate 56 and isthen pushed onto conveyor 51 by a pusher indicated at 58.

Various types of pressed ware may be produced by the machine embodyingthis invention and changes made in the construction and operation of theseveral parts without departing from the scope of the appended claims.The design of discharge device 43 may be changed to suit different typesof ware.

From the above description and the drawings, it will be seen that myinvention provides novel means whereby a narrow neck machine'may beemployed in producing either narrow neck ware or purely pressedglassware, the instrumentalities for producing the one type of warebeing quickly and easily replaced by the devices for making the othertype of ware. Also, exchangeable devices may be used for makingdifferent kinds of pressed ware.

It has not been considered necessary to illustrate herein timingmechanism for timing the automatic operation of the various parts of themachine with each other and with the feeder (not shown) for deliveringsuccessive charges of glass to funnel l2 because timing mechanism forthis purpose is disclosed in the patent to Ingle referred to above andby simple adjustments is employed in the production of either pressedware or narrow neck ware, as desired.
